BACKGROUND: Renal cell carcinoma (RCC) is the third most common malignancy in the genitourinary tract. The lungs, bone, lymph nodes, liver, and brain are common metastatic sites of RCC. However, there is limited literature on single omental metastasis of RCC.
CASE SUMMARY: We present the case of a 44-year-old man with single omental metastasis of RCC after laparoscopic radical nephrectomy. Pathological diagnosis of the resected left kidney revealed pT3a clear cell RCC (Fuhrman grade III). At 6 mo postoperatively, abdominal computed tomography revealed a 12-mm enhancing nodule in the left lower peritoneum. At 7 mo after initial operation, laparoscopic removal of the left omental nodule was performed. The pathological results indicated metastatic clear cell RCC. Currently, the patient is being treated with adjuvant pembrolizumab.
CONCLUSION: Omental metastasis of RCC owing to laparoscopic radical nephrectomy is rare. Urologists should be aware of the diverse nature of RCC.
